List methods are discussed in this article.

1. len() :- This function returns the length of list.

List = [1, 2, 3, 1, 2, 1, 2, 3, 2, 1] print(len(List)) Output: 10

2. min() :- This function returns the minimum element of list.

List = [2.3, 4.445, 3, 5.33, 1.054, 2.5] print(min(List)) Output: 1.054

3. max() :- This function returns the maximum element of list.

List = [2.3, 4.445, 3, 5.33, 1.054, 2.5] print(max(List)) Output: 5.33

## Python3

 `# Python code to demonstrate the working of` `# len(), min() and max()` `# initializing list 1` `lis ``=` `[``2``, ``1``, ``3``, ``5``, ``4``]`   `# using len() to print length of list` `print` `(``"The length of list is : "``, end``=``"")` `print` `(``len``(lis))`   `# using min() to print minimum element of list` `print` `(``"The minimum element of list is : "``, end``=``"")` `print` `(``min``(lis))`   `# using max() to print maximum element of list` `print` `(``"The maximum element of list is : "``, end``=``"")` `print` `(``max``(lis))`

Output

```The length of list is : 5
The minimum element of list is : 1
The maximum element of list is : 5
```

Output:

```The length of list is : 5
The minimum element of list is : 1
The maximum element of list is : 5```

4. index(ele, beg, end) :- This function returns the index of first occurrence of element after beg and before end.

List = [1, 2, 3, 1, 2, 1, 2, 3, 2, 1] print(List.index(2)) Output: 1

5. count() :- This function counts the number of occurrences of elements in list.

List = [1, 2, 3, 1, 2, 1, 2, 3, 2, 1] print(List.count(1)) Output: 4

## Python3

 `# Python code to demonstrate the working of` `# index() and count()` `# initializing list 1` `lis ``=` `[``2``, ``1``, ``3``, ``5``, ``4``, ``3``]`   `# using index() to print first occurrence of 3` `# prints 5` `print` `(``"The first occurrence of 3 after 3rd position is : "``, end``=``"")` `print` `(lis.index(``3``, ``3``, ``6``))`   `# using count() to count number of occurrence of 3` `print` `(``"The number of occurrences of 3 is : "``, end``=``"")` `print` `(lis.count(``3``))`

Output

```The first occurrence of 3 after 3rd position is : 5
The number of occurrences of 3 is : 2
```
